Abstract

The aim of this research is to study the fermentation technique of coconut processed liquid waste by varying the inoculum concentration of Lactobacillus acidophilus bacteria for lactic acid production. This research was carried out in several steps, namely the first step was the inoculum cultivation process of Lactobacillus acidophilus bacteria, the second step was the fermentation process of coconut water with variations in the concentration of Lactobacillus acidophilus bacteria inoculum, namely 5%, 10% and 20%. Analysis of lactic acid products, pH, glucose, Total Dissolved Solid (TDS), Total Suspended Solid (TSS) and Volatile Suspended Solid (VSS). The variation in the concentration of Lactobacillus acidophilus bacteria inoculum 20% is the most optimum to produce total lactic acid for batch and continuous systems. The results of the correlation analysis for inoculum variations of 5%, 10% and 20% had a strong relationship with lactic acid production, decreased pH and decreased glucose levels. The greater the inoculum concentration, the greater the decrease in the TDS, TSS and VSS content.

Abstract

Angle tilt is an important factor that affects the amount of solar radiation received on the surface of solar panels. Fixed-mounted solar panels cannot receive the maximum amount of solar radiation. How to get the maximum solar radiation by positioning the surface of the solar panel at a certain slope to be directly facing the sun. This study aims at  determining  the optimum slope angle of solar panels in the city of Meulaboh (4,152 LU, 96,131 BT). The method of calculating the total value of solar radiation on a sloping surface simulated with Pvsyst Software is used to determine the annual optimum tilt angle. NASA SSE solar radiation data from 1983 – 2005 were used to support simulations in this study. The results showed that the tilt angle that can produce the maximum output energy in the city of Meulaboh (4,152 LU, 96,131 BT, Johan Pahlawan) is at an angle of 5° with the orientation directly facing south.

Abstract

As the first step to air pollution control and public health protection, Air quality monitoring systems provides information that indicate the extend of pollution in an area, the source of pollution and the types of pollutants. Therefore, the aim of this study is to evaluate Jakarta’s air quality monitoring system by comparing it to the US, which participates in Indonesia’s air quality monitoring system by using their own system.  In specific, parameters such as air quality index, monitoring stations, regulation and data availability are to be compared through reviewing various literatures in detail.  The result obtained shows that the monitoring station amount is already ideal and complies to the U.S regulation. Indonesia’s ambient air quality standard need to be stricter and Air Pollutant Standard Index should include PM2.5 as a parameter obtains significantly better results. Air quality data is available and accessible, although it needs to be integrated and provide real time information in a simple and effective way.
